What we have is a wide variety of digital distribution models. I touched on this when we were discussing the different kinds of mobile platforms. Some are open, so it's whatever you want, and some are closed. Closed platforms rely on digital locks to function. With digital locks, what we often refer to as access controls also stipulate the conditions under which one can access the content.
These enable the variety we see in digital models. Without digital locks, you live in a binary world of all or nothing. You don't have the content, because no one's willing to offer it. Or you have full access to the content and you can post it online and do whatever you want with it willy-nilly. This means that as a developer of these games, you have to build that into your business model. Every single unit that's being sold has to be price adjusted for every single unit being sold out there. As a consequence, without them you're not going to be able to offer a differentiated model.
With digital locks, you can. With digital locks, you can offer a trial, for example, where someone has temporary access to your game, or access to certain levels of the game. They can try before they buy and then decide for themselves whether or not they want to purchase the game. They protect the content in digital distribution platforms like Xbox LIVE. If you didn't have digital locks, anyone could download the game from the Internet, put it onto their Xbox, and they wouldn't have to pay for it. With the digital locks in place on the Xbox or PlayStation, you find out that if you put that game in your console, it will recognize that it's a pirated game and won't let you play it.
TPMs, the digital locks, are critical to the content development of the digital economy and the e-commerce market. The reason they need to be legally protected is that they can be circumvented; they can be broken. When they're broken, it breaks the model. Without their being legally protected, anyone can go and circumvent the model, circumvent the lock that has been placed on the content, do whatever they want with it, and then make it available. That's the major problem we see.
